Title: Television receiver synchronizing arrangement
IPC: H04N5/12
Filed: 1980-05-02
Abstract: A television receiver including a synchronizing arrangement for providing line and field drive pulses for line and field output stages, which synchronizing arrangement comprises a line oscillator control circuit for controlling the frequency and/or phase of a line oscillator the output signal of which is divided by a divider circuit to produce pulses of field frequency. The divider pulses are applied to a field coincidence stage together with received field synchronizing pulses where their phases are compared and the number of times there is coincidence is counted by a counter and to a controllable switch which also receives field synchronizing pulses from a field oscillator which is driven by received field synchronizing pulses. A mode selection circuit controls the operation of switch which switch is driven into an internal synchronization mode when coincidence is present in the field coincidence stage for a given period, in which mode divider pulses drive the field output stage, and into an external synchronization mode when the above coincidence is not present, in which mode pulses from the field oscillator drive the field output stage. In order to prevent a black bar appearing for a finite period on the display tube of the receiving when changing television channel or the camera is changed in the studio the line oscillator control circuit produces an output which output drives the switch from the internal to the external synchronization mode.

Patent ES-8302081-A1 (ES)
Title: Method for manufacture of non-gelling, stable inorganic salt crutcher slurries
IPC: C11D3/20
Filed: 1981-10-20
Abstract: Gelation and setting of desirably miscible and pumpable aqueous crutcher slurries comprising sodium bicarbonate, sodium silicate and sodium carbonate are retarded and often are prevented by the addition of sodium sesquicarbonate (which serves as a source of sodium carbonate and sodium bicarbonate) after admixing of sodium bicarbonate, sodium carbonate (if added earlier) and sodium silicate. Desirably, citric acid is dissolved in the crutcher medium before addition of the sodium sesquicarbonate but its presence is not necessary. The method of the invention appreciably increases workable crutcher time (stabilizes the mix against gelation) compared to prior methods of manufacturing similar crutcher mixes of similar contents of bicarbonate and carbonate (considering the sesquicarbonate of the present method as a source of carbonate and bicarbonate), whether all the carbonate and bicarbonate are separately added to the crutcher before the silicate or are added partially before and partially after silicate addition. The improved workability and stability of the crutcher mix permit the making of higher solids content crutcher slurries, thereby resulting in significant energy savings and increases in production rates when such slurries are subsequently spray dried to produce free flowing inorganic salt base beads, from which beads built or heavy duty detergent compositions may be made by post-spraying onto the base beads a nonionic synthetic organic detergent in liquid state.

Patent ES-8800551-A1 (ES)
Title: High-speed digital loop transceiver.
IPC: H04L25/49
Filed: 1986-07-16
Abstract: A high-speed digital transceiver is provided for use in a PBX environment comprising twisted-pair wire cables interconnecting like transceivers, each transceiver being operative to exchange voice, data and control information in a packetized format over a common twisted-pair cable. Specifically, each transceiver communicates packetized pulse code modulated information in pure Alternate Mark Inverted (AMI) coding, that is, without the introduction of bipolar violation pulses to provide timing. Frame synchronization is acquired on the first pulse by the use of a digital circuit deriving synchronization from a local high-speed clock. The use of a high-speed clock-driven digital circuit for synchronization acquisition eliminates the need for a phase-locked loop synchronization scheme and its concomitant finite acquisition delay. In addition, a receiving section employs a threshold selecting circuit which switches or makes thresholds in response to an expectation of the absence any bipolar violation in the transmitted signal. The effect of intersymbol interference are further minimized by provision of digital precompensation in the transmitted signal to maximize the slew rate between consecutive pulses. The precompensation scheme is based on a knowledge of the bit pattern and the amount of energy contained in a sequence of bits.

Title: Fixed wire dilatation catheter with distal twistable segment
Inventor: SEGAR LORI K
IPC: A61M25/00
Filed: 1991-06-17
Abstract: A fixed-wire type of balloon dilatation catheter (12) has a small diameter and can be steered to and passed to and through narrow stenoses. The catheter (12) has a balloon (26) at its distal end which is collapsible to a low profile to enable it to be passed through the stenosis.

Consequently, any twisting of the catheter (12) about the wire (44) will occur distally of the balloon (26) so as not to obstruct fluid flow through the balloon (26).
